12V 100W Energy Saving Constant Temperature Heating Element Heaters for Car Small Space Heating Incubator(Black+Red)

It is a super small heater with a super small fan. It does exactly what it is supposed to do. It heats up very quickly. Not sure the durability of it but I am impressed with it. It is not something that will heat up a room. Just understand its only 2 1/4" × 2 1/4". It draws somewhere around 8 to 10 amps. I powered it directly off a solar panel just to see and it works great for what it is. I will say it heats up very quickly and you can feel it so if it doesn't heat up either there isn't enough power or its faulty.

I should have return this. Wasn’t what i needed.

It delivers 100 W but that's not.much. used for small terrarium and supplies the heat needed. Larger unit needed for more than 2 ft3. Heated air is blown out both sides. Im contacting the company to see if this right.

met my needs

The fan worked fine, but I felt no heat at all. 100W (8.3 amps at 12V) is just not enough power to produce an amount of heat that can be felt. In fact, it kind of produced a windchill.

This produced good heat, but consumes lots of power!
